The “litter marks” which has the dark color and shape like a circle was found around the oil palm tree base. These litter marks seem to be caused by the infiltration excess overland flow due to higher intensity of stemflow than the infiltration capacity of surface soil. An experiment was conducted to determine relationships between the diameter at the tree base and the radius of litter mark or infiltration area mark from the center of the stem. Result shows that the litter marks around oil palm tree base can be a useful indicator to estimate the infiltration area of stemflow-induced water.
